Studies have shown that there are differences in cooperative behavior across countries. Furthermore, differences in the use and the reaction on the introduction of a norm enforcement mechansism have been documented in cross-cultural studies, recently. We present data which prove that stark...

We present an experiment on strategic thinking and behavior of individuals and teams in oneshot normal-form games. Besides making choices, decision makers have to state their firstand second-order beliefs. We find that teams play the Nash strategy significantly more often, and their choices are...

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...

We examine the influence of guilt and trust on the performance of credence goods markets. An expert can make a promise to a consumer first, whereupon the consumer can express her trust by paying an interaction price before the expert's provision and charging decisions. We argue that the expert's...

In his seminal 1970 book, The Gift Relationship, Richard Titmuss argued that monetary compensation for donating blood might crowd out the supply of blood donors. To test this claim we carry out a field experiment with three different treatments. In the first treatment subjects are given the...

In this paper we use laboratory experiments to test the theoretical predictions derived by Villegas-Palacio and Coria (2010) about the effects of the interaction between technology adoption and incomplete enforcement. They show that under Tradable Emissions Permits (TEPs), and in contrast to...

Common identity and peer punishment have been identified as important means to reduce free riding and to promote cooperation in teamwork settings. This paper examines the relative importance of these two mechanisms, as well as the importance of income distribution in team cooperation. In a...

We compare of the performance of emission taxes between Colombia and Sweden in an experimental setting where subjects are regulated through environmental taxes and had to decide on emission levels, compliance behavior, and adoption of an environmentally friendly technology. Our design allows us...

We develop a model that relates self-control and conflict identification to cooperation patterns in social dilemmas. As predicted, we find in a laboratory public goods experiment a robust association between stronger self-control and higher levels of cooperation. This means that there is...

In an experiment, we study risk-taking of cohabitating student couples, finding that couples’ decisions are closer to risk-neutrality than single partners’ decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.
